Muteo is a fantastic example of modern Spanglish, combining the English word "mute" with the Spanish yo (-o) verb ending. You won't find this in a traditional dictionary, making it a unique word to learn from music.
In the song, Young Miko sings, "Contigo yo muteo las voces" (With you, I mute the voices). She's saying that when she's with this person, all the outside noise, criticism, and negativity disappears. It's a modern and powerful way to express finding peace and focus with someone.
Ever had a friend call you up right after a breakup? That's the whole mood of "Curita" (which means little cure or band-aid). Young Miko is on her way to help someone get over a recent heartbreak. She knows exactly what her role is, singing, "Sé que estás deja' y por eso vine... Hoy yo voy a hacer que tú la olvides" (I know you've been left and that's why I came... Today I'm going to make you forget her).
She's confident, almost cocky, about her ability to be the perfect distraction. The song is full of swagger, from spending big money—"Tú eres cara y yo gasto los thousand" (You're expensive and I spend the thousands)—to showing her off in public—"La saco a pasear y rápido to' el mundo looking" (I take her out and right away everyone's looking). It's a fun, flirty track about being the exciting rebound who helps someone move on.
